INCLUSION CRITERIA:
Non-Hodgkin's lymphomas in the following categories: Diffuse large B cell, follicular center cell grade III, anaplastic large cell, and aggressive T-cell lymphomas. Burkitt and "Burkitt-like" lymphomas in patients greater than or equal to 18 years old.
Patients with evidence of an underlying low-grade lymphoma will not be eligible for this study. This includes patients who have both indolent and aggressive histologies in the same or different biopsy sites (e.g. large cell lymphoma in a node and follicular center cell lymphoma in the bone marrow).
Diagnosis confirmed by staff of Hematopathology Section, Laboratory of Pathology, NCI. Tissue blocks from patients treated in extramural sites must be forwarded to the NCI for analysis of bcl-2 by IHC and other markers within 1 month of study entry.
Stage and Prognosis of Patients: Stage II, III, IV for all subtypes , and stage I bulky (greater than 5 cm) primary mediastinal (e.g., thymic B-cell large cell lymphomas) and Burkitt and Burkitt-like lymphomas.
No prior systemic chemotherapy. Patients may be entered if they have had prior limited-field radiotherapy or a short course of glucocorticoids for an urgent local problem at diagnosis (e.g. epidural cord compression, superior vena caval syndrome).
HIV negative.
Not pregnant or nursing.
Adequate major organ function (serum creatinine 1.5 mg/dl or creatinine clearance greater than 60 ml/min; bilirubin less than 1.5 mg/dl; ANC greater than 1,000 and platelets greater than 100,000) unless impairment is due to organ involvement by lymphoma.
No active symptomatic ischemic heart disease, myocardial infarction or congestive heart failure within the past year. If MUGA is obtained, the LVEF should exceed 40%.
No other serious concomitant medical illness or uncontrolled active infection that would jeopardize the patient's ability to receive the regimen with reasonable safety.
No history of unrelated (non-lymphomatous) neoplasms within past 5 years other than non-melanoma skin cancer or in-situ cervix cancer.
Ability to give informed consent.
